首先，它看起来像你有Visual Studio 2013和2012都安装在您的计算机上。我试着找了你提供的路径，我找不到它。在你的路径看起来像你尝试使用MVC4模板。这是我的路径：

First, it looks like you have Visual Studio 2013 and 2012 both installed on your computer. I tried looking up the path you provided, I couldn't find it. On your path it looks like you're try to use MVC4 templates. Here is my path:

C:\Program Files (x86)\Microsoft Visual Studio 12.0\
Common7\IDE\Extensions\Microsoft\Web\Mvc\Scaffolding\Templates

下面是我如何定制我的脚手架模板的BaseController：

Below is how I customized my scaffold template for the BaseController:

1）直接在项目文件夹中创建文件夹叫codeTemplate。

1)Create folder call "CodeTemplate" directly in the project folder.

2）进入下面的路径，找到MvcControllerWithActions文件夹全部复制到文件夹codeTemplates

2)Go to below path, find MvcControllerWithActions folder copy all to folder "CodeTemplates"

   C:\Program Files (x86)\Microsoft Visual Studio 12.0\
    Common7\IDE\Extensions\Microsoft\Web\Mvc\Scaffolding\Templates

3）进入codeTemplates - > MvcControllerWithActions在您的项目

3)Go to CodeTemplates -> MvcControllerWithActions in your project.

4）有两个文件，​​ Controller.cs.t4 和 Controller.vb.t4 在MvcControllerWithActions，如果你使用的是C＃，删除 Controller.vb.t4 。

4)There are two files, Controller.cs.t4 and Controller.vb.t4 in MvcControllerWithActions, if you used C#, delete Controller.vb.t4.

5）打开 Controller.cs.t4 文件，修改控制器名称BaseController，如下图所示：

5)Open the Controller.cs.t4 file, modify the Controller name to BaseController, like below:

 public class <#= ControllerName #> : BaseController
    {
    }

6）现在，当您尝试使用创建MVC5控制器添加新的脚手架项目，它会使用模板，你自定义的。

6) Now, when you try to create MVC5 Controller using "add new scaffold item", it'll use the template you customized.

希望它帮助。
